To do this, we?ll use nano to create a new configuration file called ?virtualbox.conf?. This file will go in the ?/etc/modules-load.d? directory, which contains files that need to be loaded when Arch boots up. Since adding a file to this directory requires administrative permissions, we?ll need to precede our command with ?sudo? once again.

When nano brings up the blank file, add these three lines to it:

vboxguest

vboxsf

vboxvideo

As usual, when you?re finished entering text in nano, type Control-X to exit to the command line, and answer ?y? for yes when you?re asked whether you want to save your work, and then hit ?Return? to accept the filename. At this point, reboot your machine for the Guest Additions to take effect.

One base component is our hardware detection. It is a C++ library and app and is designed after a dynamic structure. Any kind of hardware, no matter if usb or pci, can be configured by mhwd. There is just a simple configuration file which tells mhwd what to do. This way we also support hybrid graphics cards out of the box. However there are currently only mhwd configs for nvidia optimus setups. But this gap will be filled soon. Just play with some of those commands to get a feeling about mhwd.

Warning: Instead of immediately updating as soon as updates are available, users must recognize that due to the nature of Arch's rolling release approach, an update may have unforeseen consequences. This means that it is not wise to update if, for example, one is about to deliver an important presentation. Rather, update during free time and be prepared to deal with any problems that may arise.

Pacman is a powerful package management tool, but it does not attempt to handle all corner cases. Read The Arch Way if this causes confusion. Users must be vigilant and take responsibility for maintaining their own system. When performing a system update, it is essential that users read all information output by pacman and use common sense. If a user-modified configuration file needs to be upgraded for a new version of a package, a .pacnew file will be created to avoid overwriting settings modified by the user. Pacman will prompt the user to merge them. These files require manual intervention from the user and it is good practice to handle them right after every package upgrade or removal. See Pacnew and Pacsave Files for more info.
